Use LDPC

Enable Low Density Parity Check (LDPC) here.

LDPC is a method of error correction. Before the sender transmits the data packets, it expands the data stream with checksum bits depending on the modulation rate. These checksum bits allow the receiver to correct transmission errors. By default the 802.11n standard uses 'Convolution Coding' (CC) for error correction, which is well-known from 802.11a and 802.11g; however, it also provides error correction according to the LDPC-method (Low Density Parity Check).

In contrast to CC encoding, LDPC encoding uses larger packets to calculate checksums and can also recognize more bit errors. Therefore, LDPC encoding already provides a higher data rate due to having a better ratio of usage to checksum data.
